Abstract

Technologies described herein generally provide for an improved augmented reality system for providing augmented reality images comprising a pre-operative image superimposed on a patient image. The accuracy of registering the pre-operative image on the patient image, and hence the quality of the augmented reality image, may be impacted by the periodic movement of an organ. Registration of the pre-operative image on the patient image can be improved by accounting for motion of the organ. That is, the organ motion, which can be described by a dynamical model, can be used to correct registration errors that do not match the dynamical model. The technologies may generate a sequence of 3-D patient images in real-time for guided surgery.

First claim

What is claimed is:

1. A method to provide an augmented reality image, comprising:
receiving a reference image of an organ of a patient from a first imaging modality device,
wherein the reference image of the organ is a pre-operative planning image of the organ;

receiving an unregistered image of the organ of the patient from a second imaging modality device or the first imaging modality device;
determining predicted registration parameters for the unregistered image using…
